, and group 3 used natural dentifrices containing no chemical agent. White spot lesion index (WSL), gingival bleeding index (GBI), and visible plaque index (VPI) were recorded and analyzed. WSL, GBI, and VPI values exhibited no significant difference among the three groups. WSL increased significantly in group 3, GBI decreased significantly in all groups, and VPI decreased significantly in groups 1 and 2
and CPP-ACPF groups received a LASER simulation. The sounds emitted by the laser during its use will be simulated by a mobile application.All study participants will receive a tube of bleaching agent (Whiteness Simple 22%, FGM, Joinville, Brazil) and will be instructed to apply a drop of the product on the vestibular surface of each tooth on the whitening tray (up to the second premolars) and use
Clinical Comparison of LED- and Diode Laser-activated Bleaching To clinically compare the effects of LED- or Diode laser-activated bleaching on colour change, tooth-sensitivity, gingival-irritation and temperature variation over 9-months.Thirty-five patients with tooth colour A2 or higher will be included in the study. In a split-mouth design, using a 35% HP bleaching agent (Whiteness HP); one
of peroxide. However, a customized tray will be placed over the bleaching agent during entire permanence of peroxide (45 minutes). Drug: Tooth bleachingThe bleaching agent will be used in a single-application of 45 minutes.Other Name: 35% hydrogen peroxide based bleaching agent, Whiteness HP Maxx, FGM, Joinville, SC, Brazil.

. A 35% hydrogen peroxide based bleaching agent (Whiteness HP Blue, FGM, Joinville, SC, Brazil) will be mixed and applied on the vestibular surface of teeth, remaining for 40 minutes. After this time, the bleaching agent will be removed. A second session will beas carried out after 1 week following the same procedures. At this time, the patient received a single-dose capsule containing etodolac
bleaching agent (Whiteness HP MAxx Intermixx, FGM, Joinville, SC, Brazil) will be mixed and applied on the vestibular surface of teeth, remaining for 40 minutes. After this time, the bleaching agent will be removed. A second session will be carried out after 1 week following the same procedures.Evaluations:The tooth sensitivity reported by patients will be assessed using a visual analog scale (VAS
resin dam will be applied (Top Dam, FGM, Joinville, SC, Brazil) on the gingival tissue corresponding to the teeth to be bleached. A 35% hydrogen peroxide based bleaching agent (Whiteness HP Maxx, FGM, Joinville, SC, Brazil) will be mixed and applied on the vestibular surface of teeth, in the ratio of 1 drop every 3 to the thickener and peroxide, remaining for 45 minutes. After this time, the bleaching
the patients knew the content of each capsule.A light-cured resin dam will be applied (Top Dam, FGM, Joinville, SC, Brazil) on the gingival tissue corresponding to the teeth to be bleached. A 35% hydrogen peroxide based bleaching agent (Whiteness HP Maxx, FGM, Joinville, SC, Brazil) will be mixed and applied on the vestibular surface of teeth, remaining for 45 minutes. After this time, the bleaching agent
